WARNING!
Automatic pilots are designed to be a navigational aid. As an automatic steering
aid, an autopilot can alleviate the boredom of hand steering.
This allows the operator of the vessel time to attend to other duties, keep a more
accurate check of navigation duties or just relax and enjoy the trip.
HOWEVER, THE AUTOPILOT SHOULD NOT BE LEFT SOLELY IN
CHARGE OF THE VESSEL AND AN ADEQUATE WATCH SHOULD BE
MAINTAINED AT ALL TIMES.
IT IS NOT RECOMMENDED THAT THE AUTOPILOT BE USED WHILE
NAVIGATING IN RESTRICTED WATERWAYS AS WATER CURRENTS,
WIND CHANGES OR RADIO TRANSMITTER INTERFERENCE MAY
AFFCT VESSEL COURSE SUFFICIENTLY TO ENDANGER YOUR OWN
OR OTHER VESSELS.

FOREWORD
Thanks you for purchasing the ONWA KAP-866 Autopilot.
The KAP-866 Autopilot controls the vessel steering through mechanical drive,
reversing pump set, solenoid valves or relays.
The compass must be installed in a place free of magnetic interference, and
connected to the autopilot via the cable supplied.
The rudder feedback must be attached to the rudder in such a way that it can
accurately measure the position of the ship's rudder. This must also be conne-
cted to the autopilot via the cable supplied.
KAP-866 is designed and constructed to meet the rigorous demands of the
marine environment. However, no machine can perform its intended function
unless properly installed and maintained.
Please carefully read and follow the operation, installation and maintenance
procedures set forth in this manual.
We would appreciate feedback from you.
Thank you for considering and purchasing ONWA.

1.5.1 Weather Control
This setting is used for adjusting the autopilot's reponse on varies sea conditions.
The weather value sets the desired accuracy of the vesse l steering. A high
weather setting will cause the vessel to steer very accurately but may cause
excessive use of the steering.
In good weather, set this control to a high value, but ensure that the drive arrows
display on ship's heading field would not flickering continuously. This will give
the straightest possible course.
In poor weather, reduce this setting to prevent over-working the steering.
1.5.2 Rudder Control (Rudder Ratio)
This setting is used to determine the amount of rudder that the vessel requires
for steering (actually, the amount of rudder angle applied for a given angle
off course).
The centre position is usually suitable for most vessels, but also should depends
on the vessel's steering be sensitive or slow, adjustment maybe required.
In general, an agile vessel with a relatively large rudder or very small keel will
require a small rudder setting. A large, slow vessel may require a high value
for the rudder ratio.
5
This may also be adjusted according to speed, low speeds may require more
rudder angle for steering than high speeds.
A value of 1 signifies the minimum amount of applied rudder (for sensitive
steering, large rudders or low gearing ratio.
A value of 20 signifies the minimum amount of applied rudder (for vessels
with slow steering, small rudders or high gear ratio).
When the rudder setting is too low, turns will take an excessive amount of time
and the vessel may wander .
When the rudder setting is too high, turns will be rapid and the vessel will
oversteer.
1.5.3 Counter-Rudder Control
In some vessels, changing course requires a large amount of rudder to be
applied Initially, and then a smaller amount of rudder in the REVERSE direc-
tion to stop the vessel from swinging beyond its desired course. This is called
counter-rudder.
The KAP-866 Autopilot has this feature built-in. A counter-rudder setting of "1"
gives no counter-rudder steering, suitable for light and manouverable vessels.
If you find your ship over-steering when under autopilot control, increase the
counter-rudder setting by a couple of steps, and see if the next course change
behaves better.
Once the correct setting is found for your vessel, it should not need to be
changed. Unless the loading of your vessel is changed.
If you adjust the counter-rudder seting to "A" the counter-rudder functioning
automatically apply depends on the rate of vessel turning to the set course.
1.6 Follow-Up Mode
Press [FU] to change the steering mode to Follow Up and "FU" display on
the Mode field to indicate the rudder steer follows the set command angle
on the Command field.

Set rudder angle can change the course of the
autopilot :

1.7 Navigation Mode
For use when KAP-866 is interfaced to a GPS
Navigator with NMEA0183 data output.
In Navigation mode this allows the autopilot to
be directed by the GPS Navigator, enabling
automatic heading changes and eliminating the
effects of wind and tide.
The number displays on the Command field
indicates the course-to-steer,which will be the
bearing between the origin ad destination Waypoints,plus a factor to correct for
the Current crosstrack-error(XTE).
Engaging Navigation Mode
Press [ NAV] change the steering mode to Navigation mode and "NAV" display
on the Mode field to indicate the steering is directed by the connected GPS
Navigator.
The vessel will begin turnin from its current course to the course requested by
the GPS Navigation.

If no GPS data is being received by the KAP-866, the autopilot will lock onto

Setting up your GPS Navigator
Because there are a great variety of GPS Navigator that will work with this
autopilot, the following is a guide only. For more information, Please study
your GPS Navigator manual.
The GPS Navigator must be set up to output NMEA0183 data on a pair of
wires which are connected to the "GPS IN" terminal connections on KAP-866.
The data generated must include at least one of the followings:
The APA sentence.
The APB sentence.
The BOD and XTE Sentences.
If only the XTE data sentence is available, the pilot can steer in a Restricted
manner. See later in this section.
The GPS unit must then be commanded to go to a waypoint, or to follow a line
joining two or more waypoints (called a route).
This unit will then send information to the autopilot from which can be calcu-
lated the course-to-steer. IF several waypoints are linked together into a single
route, and the GPS unit is set to "auto-sequenence" between them, and an
"arrival zone" of more than 0.1 NM(Nautical Miles)is set so that the GPS can
detect when the vessel has reached a waypoint, then the KAP-866 will be able
to steer from each waypoint to the next without intervention.
If only the XTE information is available from your GPS unit then your vessel
must be on track, and heading in the correct direction before engaging the GPS
mode, and the auto-sequencing feature is not available.
8
Remember:
Prior to engaging Navigator mode, a route must be programmed into the GPS
for the Autopilot to follow.
No GPS Data Alarm
If the autopilot is not receiving valid information while in GPS Mode, the No
GPS Data alarm will sound, and "NO GPS" will blink on the display. This
counld be caused by:
Incorrect wiring of the GPS to the KAP-866.
Incorrect data output from the GPS unit.
No route set up or selected in the GPS unit.
No location fix at the GPS unit.
The bearings generated by the GPS unit must correspond to the bearings the
KAP-866 is receiving from its magnetic compass. The greater the difference
between these Bearings, the less accurate will be the Navigator mode steering.
Ensure that the GPS unit has the correct magnetic correction factor.
Ensure that the KAP-866 compass is correctly aligned and installed.
